One of the reasons I don’t like absentee ballots.
We don't have absentee-ballot snafus here because we are well-run at the county level and the rules are quite clear. Ballots which arrive in time are distributed to each individual precinct to be counted by the precinct election board on election night.
Those which do not are reviewed by the county canvassing board and only those which meet strict guidelines such as a postmark on or before election day or a military ballot properly forwarded are counted. As a result, we can conduct honest and open recounts should they become necessary rather than conduct "snafus" which . . . SHAZAM . . . discover thousands of additional ballots.
